Docker for Symfony is 1 year old!

The first birthday of the open source project “Docker for Symfony” aka D4D.LT was on December 16, 2019. The future of this project was unknown. However, after 3 months work some companies have provided us with testing server (Hostinger) and programming tools (JetBrains). The open source project “Docker for Symfony” is constantly being improved and new features are being introduced.

A few of them:
1. We improved environment file configuration. Some settings can be controlled using bash script.
2. Support all available Symfony framework versions: 2.x, 3.x, 4.x, 5.x.
3. Support another possible frameworks, e.g. CodeIgniter (CI), CakePHP, Laravel (not tested yet).
4. NodeJS version selection.

Installing VMware on 20.04: Failed to build vmmon

I found a solution on mkucebek’s github sources

rm -fdr $TMP_FOLDER
mkdir -p $TMP_FOLDER
git clone
cd $TMP_FOLDER/vmware-host-modules
git checkout $VMWARE_VERSION
git fetch
sudo make install
sudo rm /usr/lib/vmware/lib/
sudo ln -s /lib/x86_64-linux-gnu/ 
sudo /etc/init.d/vmware restart

Then, you just have to launch VMware Workstation without building modules.
